This work examines whether IT managers adopt of real options such as defer, expand, contract, and abandon in order to cope with ERP risks, which include technological risk, relationship risk with SW vendors, economic risk, and security risk. We collect data of logistics firms in Seoul and its suburbs in 2018 to empirically validate the effect of risks upon the adoption of real options. The results suggest that IT managers adopt all 4 options when facing economic risk and adopt contract and abandon options only when facing security risk. Additionally, we find that IT managers prefers expand option and avoid abandon option when they think ERP compatibility is high.

The trend of Development Projects has been changing through a few recent years. Small-scale development projects in the past were usually for building residences or officetel in a big cities. making lots of profits. These projects made not only lots of profits but also unbalance between the urban centers and the suburbs. So government made some regulations to prevent the things from being worse anymore, planned to develop the country in balance and began to lead large-scale development project such as Inno city and Newtown. At first, in this study, the phases and the characteristics of development project's change will be looked around. And then, after overview about PFV(project financing vehicle) used a lot in large-scale development projects will be seen, the better ways to use PFV in large-scale development projects are going to be proposed by considering the problems in PFV's conformation.

Land surface temperature(LST) is one of the key parameters in physics and meteorology of land-surface processes on regional and global scales. Urban Heat Island(UHI), a meteorological phenomenon by which the air temperature in an urban area increases beyond that in the suburbs, grows with the progress of urbanization. Satellite remote sensing has been expected to be effective for obtaining thermal information of the earth's surface with a high resolution. The main purpose of this study is to produce LST map of Cheongju and to analyze the spatial distributions of surface heat fluxes in urban areas. This study, taking Cheongju as the study area, aims to examine relationship between vegetation cover rates and surface temperature, and to clarify a method for calculation surface temperature with Landsat TM thermal images.

The purpose of this research is to design a road using digital photogrammatry method to generate DEM(digital elevation model) and digital ortho image based on GSIS which was applied to the road simulation. The example study area was the suburbs of Jeju city. To this study, 1/5,000 digital map and GSIS technique were used for optimum road design of the island based on Arc View software. Using this software we can Set an overlay map by combination of hill shade map, slope map, aspect map, and building buffer map. Based on this overlap map, we designed the best road line and along this line we performed three dimensional road simulation using Microstation CAD and Inroads road design programs. From the results, we found that the DEM and digital ortho image acquired from stereoairphoto using digital photogrammatry was satisfied for choosing the best roadline and the developed three dimensional road simulation technique using GSIS technique was very useful to estimate the reasonable road design before the real road construction works.

This study was attempted to segment the male consumers' market for men's suit based on brand preferences and to identify the group differences in apparel purchasing behaviors and demographic features and to suggest basic information applicable to marketing strategy. 705 men were selected for the study; they were in their twenties through forties, and they lived in Seoul and its suburbs. 655 survey questionnaires were collected and used for analysis. Using the SAS package, frequency, factors, reliability, correlation, genealogical group analysis, distribution analysis, the ($\chi$$^2$-test and the Duncan test for verification were actualized for analysis. The findings of this study were as follows: First, male-suit consumers tend to prefer the national brand(61.07%), licensed brand(19.39%), volume character brand(7.63%), prestige character brand(6.56%), and directly imported brand(5.34%) in order. Second, there were significant differences in apparel shopping orientations, purchasing behavior variables and demographic variables among the 5 classified groups.

A lifestyle changes according to environment. It appears more in the dietary life connected with the necessities in life. This study is executed empirically through the questionnaire that consists of selection attribute and variables connected with "well-being" that is examined in empirical analysis. It was carried out for 20 days from July 15 to August 5, 2003 with the customers who live in Seoul and the suburbs. With collected data, there were frequency analysis and factor analysis, reliability analysis using SPSS 10.0 packages, and T-test and ANOVA were enforced for the verification of differences between demographic elements with each factor. The result indicates that the inclinations of customers changed from the "well-being" trend have four factors: health consideration factor, food materials factor, cooking factor, and habit factor. And the housewife group shows the great changes in habit factor. In case of the changes according to incomes, the larger income earners tend to consider health more. In conclusion, people came to prefer the healthy Korean style food from the well-being trend.

This study is to design aged institutional household on a small scale, also the purpose of this study is to provide basic material for management of small scale institutional household and policy establishment that could help the aged well-being. Design of research is accomplished after the review of related literatures. The propositions of design are 3s follows; region：seoul suburbs(2 hours' distance) building：fourth stories(The building-to-land ratio 25％, capacious ratio 100％, in environmental affinity.) object：75 years and over aged 15 women cost：deposit and living month expenses contract between the manager and the desired occupant or concerned family term of validity：As long as occupant want.

The purpose of this research is to examine the evolution of low-cost sales housing and give suggestions for the future housing for the 21st century. This paper investigates the trends of low-cost suburban housing since world War II, as examplified by the Levitt housing in the Northeastern regions of the States. This research analyzes the trends of 14 variables including total floor area. lot size, living room size, kitchen size, mean bedroom size, master bedroom size, number of bedrooms, number of bathrooms, family room, garage, number of story, appliances and features, values, and values per sq ft. Nine entry-level houses were chosen as cases for comparative purpose at different points in time from 1940's to 1990's. This research finds that house sizes have been grown until 1960s, but this trend has reversed with shrinking economy and changing family lifestyles. The trend for smaller housing equipped with several features and convenient equipments will be continued for the next decades to come.

Kyoto, which was Japan's political and cultural capital for more than a millennium before the dawn of the modern era, shows distinctive characteristics formed in the process of urban modernization. A citizen plaza perfectly fit to a modern city is lying on the east side, but a delayed urban reconstruction in the city center due to a strong conservative self-government awareness, as well as a delayed modernization of tax system, caused disorderly urban sprawl to appear in the suburbs. Thanks to the enactment of urban planning law enacted in 1919 by the government (Ministry of Internal Affairs) and an increasing awareness about the necessity and rationality of urban planning projects, urban renovation took place at a rapid pace. In the meantime, new ways of urban design were sought for and experimented to conserve it as a historical city against the city' quickly changing landscape.

우리는 한국동굴학회의 요청과 사업계획에 따라, 동북-중앙아시아지역 동굴과학정보망 구축 사업에 동의하고 이를 기원하는 뜻으로 중국 길림성 연변조선족자치주 화룡시 근교의 충천계곡(골)자연동굴을 탐사하였다. 이를 위하여 1년 전 어느 날 화룡시 충천 골에 있는 동굴을 찾아 연길에서 차를 타고 장인촌으로 간 적이 있었다. 그곳에 가서 수소문하여 동굴에 대해 잘 알고 계신다는 김창현 노인을 찾았다. 당시 우리가 그 노인을 찾았을 때는 이미 점심때가 다 되었다. 우리가 동굴을 찾아가 보려고 김창현 노인을 찾아왔다고 하자, 그 노인은 동굴이 이곳에서 멀리 떨어져 있어서 아침 일찍 떠나야 하기에 오늘은 갈 수 없다고 하였다. 그리하여 우리는 김 노인으로부터 동굴에 대한 이야기만 좀 듣고 돌아와서 후에 약속한 날에 다시 탐사방문을 추진하기로 결정하였고, 바로 이때부터 우리는 국제교류와 협력을 통하여 사실상 국제동굴과학정보망 구축 사업에 동참을 시작한 셈이 되었으며, 이를 적극 지지한다.
